only used this bag a handful of times. a pen exploded in one of the small pockets inside and i couldn’t really sort out how to clean it off but the outside of bag is fine, otherwise great condition! i have the dust bag. it has one 1/2 keychains still on it as well. fits a 15” laptop, 2 stanley sized water bottles. i believe many people use as a diaper bag, i used for work, but super roomy and versatile. it has a long shoulder strap that can be converted to backpack strap
